As an online Poker player, the most important factor for me is to make sure that all my co-players within the table is a legit person and not a bot. It is my most concern of all things in poker and until I don't know how to verify it unless they are chatting in the chatbox. 
indeed this is disadvantages from playing poker at online sites because poker online is very vulnerable to rigging and possibly our opponents is the bots or the admin themself but to avoid the problem just like this i think only choose online poker with good reputations with good review from the players
